Now you try the tool on our own to create a graph. Use the data set “Sleep Study – Class Year” to create a bar graph to show the class years of the college students in the study. Make sure they are in the appropriate order. Look back to the steps above for guidance as needed.

[Wrap-up: “What did you discover? Did you find evidence for underage drinking? We saw that there were many sophomores involved in the study and we saw that many students responded that they drank “moderately.” Do you feel the combination of these two variables points to underage drinking being present at the survey school? There are other good questions to ask about this data, as well. Do you think there would be a relationship between alcohol and academic performance? What about alcohol and sleep? Before we move on to the next section, let’s recap the objectives for this activity. [voice over the list at the top of the page, or move through the page using jump links] You’ve identified the categorical variables in the data set and used technology to create frequency tables, bar graphs, and pie charts, then used those displays to answer research questions about the data. We’ll return to this study in future sections of the course to investigate other questions: would owls drink more than larks? Are different class levels more likely to be larks or owls? These are all good questions. Can you think of others?”]
